Geodetic Transformations Models- the 'Grid Look Up Table' for OSTN02 The OSTN02 (2002) national ‘definitive transformation’ is an accurate realization (conversion) between OSGB36 National Grid and ETRS89 (1989) coordinates. To achieve the re-projection, a 7 parameter (3 shifts, 3 rotations and a scale change) transformation is required. The OSTN02 transformation is modeled as a 1km grid of varying parameters which...
